1. A method of operating a network station, the method comprising:

  • determining a framing of a cooperative network transmission on a first frequency;

    scheduling an asynchronous detection interval within a frame defined by the identified framing of the cooperative network;

    detecting for non-cooperative transmissions on the first frequency during the asynchronous detection interval, the non-cooperative transmissions originating from a source not participating in the cooperative network;

    detecting for non-cooperative transmissions on a second frequency;

    determining that the first frequency is occupied based upon a presence of a non-cooperative transmission detected on the first frequency;

    determining that the second frequency is not occupied based upon an absence of non-cooperative transmissions detected on the second frequency;

    tuning a receiver to the second frequency responsive to information regarding occupancy of the first and second frequencies; and

    receiving a transmission from a cooperative network station on the second frequency.
